Electronic Nautical Chart (ENC)

An Electronic Nautical Chart (ENC) is a digital map used by ships' navigation systems that provides detailed, accurate information about waterways, including depths, coastlines, navigational aids, and hazards. Designed for real-time use, ENCs help mariners plot safe courses efficiently, replacing traditional paper charts. They are created with precise geographic data and are integrated into electronic chart display and information systems (ECDIS), enhancing safety by allowing ships to respond quickly to changing conditions and ensuring compliance with international navigation standards.
